High Hopes: In The House of Blue Leaves, zoo-keeper Artie Shaughnessy (Ben Stiller) dreams of becoming a Hollywood songwriter and his mistress, Bunny Flingus (Jennifer Jason Leigh), will do anything to help him get there. Forty years ago, Stiller's mother played Bunny in the original off-Broadway production. And in 1986, Stiller played the role of Artie's son. (Joan Marcus)
